.SYNOPSIS FOR NEW ENGLAND WATERS...A high pressure ridge
extending W over the northern waters will continue tonight into 
Sat night while slowly weakening. A warm front just S of the 
area will drift N over the waters tonight and Sat, and become 
nearly stationary over the southern waters Sat night as a low
pressure center moves E and NE along the front. The front will 
gradually weaken Sun and Sun night as the low pressure center
passes E of the area, before the front dissipates Mon. A cold 
front will approach from the NW late Mon into Mon night, move SE 
across the northern waters later Mon night into Tue, then pass E 
of the area later Tue. Another low will approach the region from
the SW Tue night, and move NE across the waters Wed while
